Do you have any suggestions on the construction and installation of emergency broadcasting?

In order to establish and install emergency broadcast, we suggest the following:

Cable broadcasting system: This is a traditional emergency broadcasting scheme, which usually requires the installation of cable broadcasting lines and speakers, and is widely used in schools, public places and offices. Its advantages are stability, reliability and wide coverage, and it is suitable for large-scale places.

Translation broadcasting system: This scheme usually adopts digital signal transmission system and wireless speakers, which can support multilingual broadcasting and is suitable for institutions, education, medical care and other places.

Wireless network playback system: This scheme adopts wireless Internet technology, and can be played anywhere with Internet access without installing wired speakers. This scheme is suitable for places with multiple branches, such as hotels and hospitals with multiple conference rooms.
